IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 196,744, dated November 6, 1877; application filed June 30, 1877.

To all whom it may concern:

Be it known that I, RUDOLPH OoRETH, of Belleville, in the county of St. Clair and State of Illinois, have invented a new and useful Improvement in Plows, which improvement is fullyset forth in the following specification and accompanying drawings, in which latter Figure l is a view of my improved plow Fig. 2 is a view of the same from the opposite side. Fig. 3 is a transverse section in the line a: w of Fig. 1.

The nature of my invention consists in certain constructions, combinations, and arrangements of parts, hereinafter fully described and specifically claimed, whereby a plow with an improved mold-board is produced; the object of which is to enable the operator to free the said mold-board from adhering soil or clay, during the operation of plowing, without stopping the plow or takingit out of the ground.

In the drawings, Arepresents the plow-share of my improved plow; B, the land -side, and G the standard, which three parts may be constructed in any ordinary mode as used at the present time. To the said parts I fit a moldboard, D, in a suitable manner, which moldboard has a number of slots or openings, d, in its operating surface, and into these openings a number of slats or bars, 0, are loosely fitted,- in such manner that they may be moved either above or below the said surface, or flush with the same. I unite the said bars 0 by transverse braces E, with which they are either cast together or otherwise united.

The braces E are at the back of the moldboard, and are cut away, as at f, so as to allow the movable bars 0 to freely pass between the grate-bars d of the mold-board D and in the slots 01 thereof.

The movable bars o and their braces E are supported and operated, at the back of the mold-board, by a hand-lever, F, which, to make laterally steady, is forked above its fulcrums f, as shown. From the forked portions of the lever F, links 9 and g form an articulating connection with the lower parts of two of the bars 0, as indicated in Figs. 2 and 3.

In order to obtain a uniform leverage or a parallel motion of the bars ewhen operated by the lever F, I make use of an intermediate lever, H, as shown in Fig. 2, which has a stationary fulcrum, h, on the'mold-board, and is connected to the lever F by means of a slot, h, and a pin, f. This lever H, at a suitable point between its fulcrum h and slot h, is connected, by means of a pin, 6, and a lug, I, to the upper brace E.

The described arrangement and connections of the levers F and H and connecting-links g and g'gives the same amount of leverage and movement to the upper and lower ends of the movable bars 6, as well as a simultaneous and parallel motion, when the lever F is moved.

The fulcrums f of the lever F are uponlugs g of a transverse bar, G, which may be fastened between themold-board and land-side.

The normal position of the bars e is such that they present a smooth and even surface with grate-bars (1 This position of the bars 6 maybe maintained or secured by means of a notch, j, in a steady-bar, J, on the moldboard, into which notch the lever F is sprung when the plowing goes on smoothly.

I havemade the movable bars 0 and gratebars d of triangular sectional shape for the purpose of strengthening them; but any other shape which answers the said purpose may be adopted without changing the principle of my invention. The same may be said of the connections between the lever F and the bars 0, which connections may be attached directly to the said bars 6 or to the braces E.

Operation: In ordinary plowing thenormal position of the bars 0 is maintained in the aforesaid manner; but when the soil is wet and very tough it will adhere to the mold-board and coat it over thickly, thereby causing the furrow-slice to turn over irregularly and break into pieces. The common practice heretofore insuch cases has been to stop the team, draw the plow from the furrow, and with a paddle or scraper remove the adherent muck from the mold-board.

If it is found that my mold-board becomes 7 coated with muck or tough soil, the driver or plowman keeps on plowing, removes the lever F from the notch j, and, by moving it up and down several times, moves the bars 6 above and below the stationary part of the moldboard surface. This operation-causesthe coating of soil or muck on the mold-board to be broken into small transverse slices or fragments, which are readily pushed oil the moldboard and the bars e by the passing furrowslice. The lever F is then replaced in the notch j without interruption of the plowing operation. 1 The main part of my invention is the mode of breaking up and removing the soil from the mold-board during the passage of the plow in the ground, and the manner of constructing the mold board of stationary and movable parts, over which the furrow-slice must pass;

therefore any other mold-board, with movable bars or grates with any other motion--as, for instance, bars swung on hinges, and so onwould only be a modification of my invention, without changing its principle of operation.

Having described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The movable bars 0, in combination with the skeleton mold-board D, substantially in the manner and for the purpose set forth.

2. The combination of the bars 0, braces E, links g g levers H and F, and the slotted mold-board D, substantially as set forth.

Witness my hand, in the matter of my application for a patent for a plow, this 26th day of June, A. D. 1877.
